Description

La présente invention concerne une serrure électronique, et plus partculièrement une telle serrure agencée pour coopérer avec une clef munie d'une pluralité de mémoires programmables, ladite serrure comportant un organe d'actionnement, une mémoire morte contenant un code, et des moyens de comparaison pour comparer successivement ledit code contenu dans la mémoire morte avec les codes contenus dans les mémoires programmables de la clef.The present invention relates to an electronic lock, and more particularly such a lock arranged to cooperate with a key provided with a plurality of programmable memories, said lock comprising an actuating member, a read-only memory containing a code, and comparison means. to successively compare said code contained in the read-only memory with the codes contained in the programmable memories of the key.

Une telle serrure est connue par exemple par la demande de brevet francais N° 8700764. Cette demande prévoit notamment la possibi­lité d'assurer l'alimentation des différents circuits électroniques de la clef et de la serrure à partir d'une pile contenue dans la clef. Elle prévoit également de laisser tourner librement le barillet de la serrure lorsque cette dernière est inactive, et de ne le solidariser du pêne qu'après qu'un des codes de la clef a été reconnu.Such a lock is known, for example, from French patent application No. 8700764. This application provides in particular the possibility of supplying power to the various electronic circuits of the key and of the lock from a battery contained in the key. . It also provides for the barrel of the lock to rotate freely when the latter is inactive, and to secure it to the bolt only after one of the codes of the key has been recognized.

Il en résulte que la quantité d'énergie disponible est néces­sairement faible puisqu'elle doit être compatible avec le volume et le poids d'une clef. Il n'est donc pas possible de maintenir actifs les circuits électroniques de la clef et de la serrure entre le moment où le code a été reconnu et le moment où l'on souhaite manoeuvrer la ser­rure.As a result, the quantity of energy available is necessarily low since it must be compatible with the volume and the weight of a key. It is therefore not possible to keep the electronic circuits of the key and of the lock active between the moment when the code has been recognized and the moment when it is desired to operate the lock.

La présente invention vise à résoudre ce problème en fournis­sant une serrure du type décrit ci-dessus, qui se comporte comme une serrure classique dès lors que le code a été reconnu, et dont la seule consommation d'énergie résulte d'une part de la reconnaissance du code et d'autre part de la solidarisation instantanée du barillet avec le pêne lorsque le code a été reconnu.The present invention aims to solve this problem by providing a lock of the type described above, which behaves like a conventional lock once the code has been recognized, and whose only energy consumption results on the one hand from the recognition of the code and on the other hand of the instantaneous fastening of the barrel with the bolt when the code has been recognized.

A cet effet, l'invention a pour objet une serrure électroni­que agencée pour coopérer avec une clef munie d'une pluralité de mémoi­res programmables, ladite serrure comprenant un organe d'actionnement, une mémoire morte contenant un code, et des moyens de comparaison pour comparer successivement ledit code contenu dans la mémoire morte avec les codes contenus dans les mémoires programmables de la clef, caracté­risée par le fait qu'elle comprend des moyens d'engrènement entre la clef et l'organe d'actionnement, un électro-aimant agencé pour comman­der lesdits moyens d'engrènement lorsque les moyens de comparaison ont reconnu l'identité entre un code de la clef et le code de la serrure, et des moyens de blocage pour maintenir les moyens d'engrènement en position engrénée jusqu'à ce que la clef soit retirée de la serrure.To this end, the subject of the invention is an electronic lock arranged to cooperate with a key provided with a plurality of programmable memories, said lock comprising an actuating member, a read-only memory containing a code, and comparison means for successively compare said code contained in the read-only memory with the codes contained in the programmable memories of the key, characterized in that it comprises means of engagement between the key and the actuating member, an electromagnet arranged to control said means of engagement when the means comparison have recognized the identity between a key code and the lock code, and blocking means to maintain the engagement means in the engaged position until the key is removed from the lock.

Un tel agencement constitue en quelque sorte une mémoire mécanique. Dès lors que l'un des codes de la clef a été reconnu comme valide, une seule impulsion suffit à amener en prise la clef et l'or­gane d'actionnement, qui y demeure jusqu'à ce que la clef soit retirée de la serrure.Such an arrangement constitutes in a way a mechanical memory. Once one of the key codes has been recognized as valid, a single pulse is enough to engage the key and the actuator, which remains there until the key is removed from the lock .

La clef peut alors être actionnée à tout instant sans qu'il en résulte de consommation d'énergie supplémentaire.The key can then be activated at any time without resulting in additional energy consumption.

Un autre avantage découle d'un tel agencement. Si, en effet, la clef est utilisée pour verrouiller un local depuis l'intérieur, il suffit de la laisser en place pour pouvoir le déverrouiller en toute circonstance y compris en cas de défaillance de la source d'énergie, ou des systèmes électroniques, puisque la serrure se comporte alors comme une serrure classique, tant que la clef n'a pas été retirée.Another advantage arises from such an arrangement. If, in fact, the key is used to lock a room from the inside, it is enough to leave it in place to be able to unlock it in all circumstances, including in the event of failure of the energy source, or electronic systems, since the lock then behaves like a conventional lock, as long as the key has not been removed.

On notera donc que, bien que l'invention soit notamment desti­née au cas où l'alimentation électrique s'effectue à partir de la clef, elle présente également des avantages importants sur le plan de la sécurité dans le cas où cette alimentation est effectuée à partir de la serrure.It will therefore be noted that, although the invention is in particular intended for the case where the electrical supply is made from the key, it also has significant advantages in terms of safety in the case where this supply is carried out at from the lock.

Dans un mode de réalisation particulier de l'invention, les­dits moyens d'engrènement comprennent un organe mobile solidaire en rotation de la clef et susceptible d'être amené en position d'engrène­ment avec l'organe d'actionnement sous l'action de moyens élastiques lorsque l'électro-aimant est activé, ledit organe mobile étant agencé pour empêcher l'électro-aimant de revenir en position inactivée aussi longtemps que cet organe mobile est en position d'engrènement.In a particular embodiment of the invention, said engagement means comprise a movable member integral in rotation with the key and capable of being brought into engagement position with the actuating member under the action of means elastic when the electromagnet is activated, said movable member being arranged to prevent the electromagnet from returning to the inactivated position as long as this movable member is in the engagement position.

Plus particulièrement, la serrure selon l'invention peut com­prendre un organe de verrouillage agencé pour être déplacé par la clef contre l'action de moyens élastiques, d'une position où il empêche l'or­gane mobile de venir en position d'engrènement à une position où il autorise la libération de l'organe mobile par l'électro-aimant.More particularly, the lock according to the invention may comprise a locking member arranged to be moved by the key against the action of elastic means, from a position where it prevents the movable member from coming into engagement position at a position where it authorizes the release of the movable member by the electromagnet.

On décrira maintenant, à titre d'exemple non limitatif, un mode de réalisation particulier de l'invention en référence aux dessins schématiques annexés dans lesquels :

  • les figures 1A à 1E sont des coupes verticales axiales d'une demi-serrure selon l'invention illustrant les différentes étapes de son fonctionnement;
  • la figure 2 est une vue en coupe selon la ligne II-II de la figure 1A; et
  • la figure 3 est une vue en coupe selon la ligne III-III de la figure 1A.
A particular embodiment of the invention will now be described, by way of nonlimiting example, with reference to the appended schematic drawings in which:
  • FIGS. 1A to 1E are axial vertical sections of a half-lock according to the invention illustrating the different stages of its operation;
  • Figure 2 is a sectional view along the line II-II of Figure 1A; and
  • Figure 3 is a sectional view along line III-III of Figure 1A.

La demi-serrure représentée aux dessins comprend d'une ma­nière générale un canon 1 à l'intérieur duquel un barillet 2 est monté à rotation et retenu axialement à l'aide d'une goupille 3 coopérant avec une rainure 4. L'autre demi-serrure lui est symétrique de manière à permettre le verrouillage et le déverrouillage de l'un ou l'autre côté de la porte sur laquelle est montée la serrure.The half-lock shown in the drawings generally comprises a barrel 1 inside which a barrel 2 is rotatably mounted and held axially by means of a pin 3 cooperating with a groove 4. The other half -lock is symmetrical so as to allow locking and unlocking on either side of the door on which the lock is mounted.

Un organe d'actionnement 5 est également monté tournant sur le canon 2, et est muni d'un doigt d'entraînement 6 pour entraîner le pêne (non représenté) de la serrure.An actuating member 5 is also mounted rotating on the barrel 2, and is provided with a drive finger 6 to drive the bolt (not shown) of the lock.

Le barillet 2 comporte un orifice 7 pour recevoir une clef 8 (figure 1B), cet orifice comportant des encoches 9 susceptibles de coopérer avec des saillies 10 de la clef pour permettre l'entraînement du barillet en rotation sous l'action de la clef.The barrel 2 comprises an orifice 7 for receiving a key 8 (FIG. 1B), this orifice comprising notches 9 capable of cooperating with projections 10 of the key to allow the barrel to be driven in rotation under the action of the key.

La clef 8 comporte, comme décrit dans la demande française précitée, une pile pour l'alimentation électrique de ses propres cir­cuits et de ceux de la serrure, ainsi qu'un ensemble de mémoires pro­grammables contenant des codes.The key 8 comprises, as described in the aforementioned French application, a battery for the electrical supply of its own circuits and those of the lock, as well as a set of programmable memories containing codes.

Un organe de verrouillage 11 est monté coulissant dans un évidement du barillet 2 pour se déplacer en translation, vers le haut dans les figures, contre l'action de deux ressorts hélicoïdaux 12, disposés en compression entre l'organe 11 et le barillet 2. Cet organe de verrouillage comporte un plan incliné 13 susceptible de coopérer avec un plan incliné correspondant 14 de la clef de manière que, lors de son introduction, cette dernière repousse l'organe 11 vers le haut en comprimant les ressorts 12.A locking member 11 is slidably mounted in a recess of the barrel 2 to move in translation, upwards in the figures, against the action of two helical springs 12, arranged in compression between the member 11 and the barrel 2. This locking member comprises an inclined plane 13 capable of cooperating with a corresponding inclined plane 14 of the key so that, when it is introduced, the latter pushes the member 11 upwards by compressing the springs 12.

La serrure comporte également un organe mobile 15 coulissant dans le barillet 2, déplaçable vers le haut sous l'action d'un ressort hélicoïdal 16 comprimé entre cet organe mobile et le barillet 2.The lock also comprises a movable member 15 sliding in the barrel 2, movable upwards under the action of a helical spring 16 compressed between this movable member and the barrel 2.

Les ressorts 12 possèdent une raideur supérieure au ressort 16 pour une raison qui sera exposée ci-après.The springs 12 have a greater stiffness than the spring 16 for a reason which will be explained below.

L'organe mobile 15 comprend une partie d'extrémité 17 située du côté du ressort et agencée pour s'engager dans des renfoncements 18 de l'organe d'entraînement 5 sous l'action du ressort 16, après qu'il a été libéré comme cela sera décrit ci-après.The movable member 15 comprises an end portion 17 located on the side of the spring and arranged to engage in recesses 18 of the drive member 5 under the action of the spring 16, after it has been released. as will be described below.

Dans la position de repos de la serrure représentée à la figure 1A, l'organe mobile 15 est maintenu dans sa position basse con­tre l'action du ressort 16, comme cela sera décrit ci-après, et l'or­gane de verrouillage 11 est maintenu par les ressorts 12 dans sa posi­tion basse en appui contre l'organe mobile 15.In the rest position of the lock shown in FIG. 1A, the movable member 15 is held in its low position against the action of the spring 16, as will be described below, and the locking member 11 is held by the springs 12 in its low position bearing against the movable member 15.

La serrure comprend également une fibre optique 19 agencée pour transmettre à une électronique 20 les codes contenus dans les mémoires programmables de la clef par l'intermédiaire d'une cellule de réception 21.The lock also comprises an optical fiber 19 arranged to transmit to an electronic device 20 the codes contained in the programmable memories of the key via a reception cell 21.

Comme décrit également dans la demande française précitée, l'électronique 20 comprend au moins une mémoire morte contenant un code caractéristique de la serrure, et des moyens pour comparer ce code aux codes reçus de la clef.As also described in the aforementioned French application, the electronics 20 comprises at least one read-only memory containing a code characteristic of the lock, and means for comparing this code with the codes received from the key.

L'électronique 20 est montée sur une platine 22 qui reçoit également un électro-aimant 23 dont le plongeur 24 est diposé de telle sorte que, lorsque l'électro-aimant 23 n'est pas activé, il coopère avec une surface de l'organe mobile 15 pour le retenir et l'empêcher de se déplacer vers le haut sous l'action du ressort 16.The electronics 20 is mounted on a plate 22 which also receives an electromagnet 23 whose plunger 24 is provided so that, when the electromagnet 23 is not activated, it cooperates with a surface of the movable member 15 for retaining it and preventing it from moving upwards under the action of the spring 16.

Enfin deux connexions électriques 25 entourées d'une gaîne isolante 26 sont disposées dans le barillet 2 pour assurer l'alimenta­tion électrique de l'électronique 20 à partir de la pile contenue dans la clef.Finally, two electrical connections 25 surrounded by an insulating sheath 26 are arranged in the barrel 2 to supply electrical power to the electronics 20 from the battery contained in the key.

On notera que, dans la position représentée à la figure 1A, le barillet 2 peut tourner librement dans le canon 1 de la serrure sans entraîner l'organe d'actionnement 5, ce qui limite grandement les ris­ques d'effraction.Note that, in the position shown in Figure 1A, the barrel 2 can rotate freely in the barrel 1 of the lock without driving the actuating member 5, which greatly limits the risk of burglary.

Lorsque la clef 8 est introduite dans l'orifice 7, comme montré à la figure 1B, elle repousse l'organe de verrouillage 11 vers le haut, autorisant ainsi la libération de l'organe mobile 15 par le plongeur 24.When the key 8 is inserted into the orifice 7, as shown in FIG. 1B, it pushes the locking member 11 upwards, thus authorizing the release of the movable member 15 by the plunger 24.

Les codes contenus dans les mémoires programmables de la clef sont alors adressés successivement à l'électronique 20 qui les compare au code contenu dans sa mémoire morte jusqu'à ce que l'identité entre deux codes soit reconnue. Une impulsion est alors appliquée à l'électro-aimant 23 qui provoque la rétraction du plongeur 24 comme représenté à la figure 1C, ce qui libère ainsi totalement l'organe mobile 15.The codes contained in the programmable memories of the key are then sent successively to the electronics 20 which compares them to the code contained in its read-only memory until the identity between two codes is recognized. A pulse is then applied to the electromagnet 23 which causes the plunger 24 to retract as shown in FIG. 1C, which thus completely releases the movable member 15.

Celui-ci commence alors à se déplacer vers le haut comme représenté à la figure 1D. Si la partie 17 de cet organe ne se trouve pas en face d'un renfoncement 18 de l'organe d'actionnement 5, il reste en appui sur la surface intérieure de ce dernier comme cela est le cas dans la figure 1D. Il suffit alors de provoquer une légère rotation du canon à l'aide de la clef, au maximum égal à un quart de tour, pour que la partie 17 de l'organe 15 s'engage dans un des renfoncements 18, soli­darisant ainsi la clef et l'organe d'actionnement par l'intermédiaire du canon 2 et de l'organe 15.This then begins to move upward as shown in Figure 1D. If the part 17 of this member is not opposite a recess 18 of the actuating member 5, it remains in abutment on the inner surface of the latter as is the case in FIG. 1D. It then suffices to cause a slight rotation of the barrel using the key, at most equal to a quarter turn, so that the part 17 of the member 15 engages in one of the recesses 18, thus securing the key and the actuating member via the barrel 2 and the member 15.

On remarquera que, dès lors que l'organe mobile 15 a commencé son déplacement vers le haut, le plongeur 24 de l'électro-aimant 23 ne peut plus revenir en position inactivée, de sorte qu'une seule brève impulsion appliquée à l'électro-aimant 23 suffit pour provoquer l'engrè­nement de la clef avec l'organe d'actionnement 5.It will be noted that, as soon as the movable member 15 has started its upward movement, the plunger 24 of the electromagnet 23 can no longer return to the inactivated position, so that a single brief pulse applied to the electromagnet 23 is sufficient to cause the engagement of the key with the actuating member 5.

En effet, l'extrémité du plongeur est alors en appui sur une surface frontale 27 de l'organe mobile 15 qui l'empêche de ressortir du corps de l'électro-aimant 23.Indeed, the end of the plunger is then supported on a front surface 27 of the movable member 15 which prevents it from coming out of the body of the electromagnet 23.

Ce n'est que lorsque la clef est retirée de la serrure qu'elle libère l'organe de verrouillage 11, de sorte que celui-ci reprend sa position initiale sous l'action des ressorts 12 en entraî­nant vers le bas l'organe mobile 15 contre l'action du ressort 16. La raideur supérieure des ressorts 12 permet ce mouvement.It is only when the key is removed from the lock that it releases the locking member 11, so that the latter returns to its initial position under the action of the springs 12, driving the movable member downwards. 15 against the action of the spring 16. The upper stiffness of the springs 12 allows this movement.

Lorsque l'organe mobile reprend sa position initiale, il libère le plongeur 24 qui revient à sa position initiale, empêchant ainsi toute nouvelle solidarisation du canon 2 avec l'organe d'actionne­ment 5 jusqu'à ce qu'une nouvelle impulsion soit appliquée à l'électro-­aimant 24.When the movable member returns to its initial position, it releases the plunger 24 which returns to its initial position, thus preventing any further securing of the barrel 2 with the actuating member 5 until a new pulse is applied to the electromagnet 24.

Diverses variantes et modifications peuvent bien entendu être apportées à la description qui précède sans sortir pour autant du cadre ni de l'esprit de l'invention.Various variants and modifications can of course be made to the above description without departing from the scope or the spirit of the invention.

C'est ainsi en particulier qu'il n'a été question que d'une seule mémoire morte contenant un seul code dans l'électronique 20. Il est bien entendu que cette électronique pourrait contenir plusieurs codes susceptibles d'être activés sélectivement au gré du possesseur de la serrure.Thus, in particular, only a single read-only memory containing a single code was discussed in the electronics 20. It is understood that this electronics could contain several codes capable of being activated selectively at will. of the owner of the lock.
